Firmly grasp the top and bottom motherboards in opposite hands, then gently pull them apart.

The top motherboard is still connected to the bottom motherboard. To fully separate the top motherboard, you will need to use a soldering iron.

Warning: Do not attempt to disconnect the shielded (gold colored) connector as it is extremely fragile you will break it. It runs between the two boards.

De-solder the shielded cable from the lower board instead of attempting to disconnect the connector. De-solder using micro soldering techniquest.
